If you just need a couple of endpoints just to expose computations to the outer world, I’d go with HttpServer.jl - it’s very basic and low-level, but worked well for me a couple of times. If you need more complex routing, Mux.jl should a better fit. Genie.jl is more like Django in Python world: it’s server + ORM + templates, etc., for me it turned to be an overkill. No idea what HTTP.Server is about, so you’d need to figure it out yourself.
